Blue Jays' Roberto Osuna: Not available Saturday

Osuna will not be available out of the bullpen for Saturday's game against the Orioles, Brendan Kennedy of the Toronto Star reports.

Jason Grilli will serve as the Blue Jays' closer Saturday should a save situation arise because Osuna has pitched the last two days and three of the last four days overall. Osuna figures to be ready to close Sunday following his day off.
